Frequently Asked Questions

ETMoses is constantly evolving, either by new features being added or existing ones being improved. You can keep track of the current developments by looking at the list of open GitHub issues. This wiki will be updated to reflect these changes and can therefore be considered as a living document.

This page is intended to list the more frequently asked questions and their answers.

• How does the units attribute of nodes work with the undelying children?

The 'units' keyword has a special function: it multiplies the capacity and investment cost of the component. This can be used to group many components of the same type. No other attributes of the component are multiplied by the 'units'. This also holds for the 'children'. The user is responsible for keeping things consistent: e.g. if you increase the capacity of a node, the capacities of its children will not be increased. If you would like these capacities to increase as well, you need to update them manually.

• What is the effect of changing technology attributes?

You can change all attributes of all technologies to fit your own needs. These changed attributes will be taken into account in ETMoses. However, when you scale your scenario back into a national scenario (see the Quick start guide on how to do so), these changed attributes will be ignored.

• What are the advantages of making separate nodes for separate houses and what for one node for a group of houses / When can you better ... in the topology and when in the technology tabel

If you model de houses separately as a node, you can specify the capacity and investment cost and the like individually, when you take them as a group at a node you have to add up the capacities/ investment of the houses. ...
